AJAX :: After The Upgrade To 4.0 The Linkbutton Causes A Full Postback With Page Refresh?

Jun 15, 2010

I have an update panel with content that needs to be updated by a listview item which is a linkbutton, in .NET 3.5 I just used the defaults on all the controls and everything worked fine, after the upgrade to 4.0 the linkbutton causes a full postback with page refresh. I did try setting the linkbutton's id as the trigger for the update panel and still causes same page refresh. The scriptmanager is on the masterpage with enablepartialrendering = true.

AJAX :: Child Elements In LinkButton Break UpdatePanel Functionality, Cause Full Postback

Apr 21, 2010

If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.

Updating Div After Full Page Refresh Following AJAX Request?

Jun 9, 2010

I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded.

How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)

UpdatePanel With GridView With LinkButton With Image Causes Full Postback

Apr 20, 2010

So this might be a fairly specific issue but I figured I'd post it since I spent hours struggling with it before I was able to determine the cause.

<asp:GridView ID="gvAttachments" DataKeyNames="UploadedID" AutoGenerateColumns="false" OnSelectedIndexChanged="gvAttachments_SelectedIndexChanged" runat="server">
<EmptyDataTemplate>There are no attachments associated to this email template.</EmptyDataTemplate>
<Columns>
<asp:TemplateField ItemStyle-Width="100%">
<ItemTemplate>
<asp:LinkButton CommandName="Select" runat="server"><img src="/images/icons/trashcan.png" style="border: none;" /></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

In the ItemTemplate of the TemplateField of the GridView I have a LinkButton with an image inside of it. Normally I do this when I have an image with some text next to it but this time, for whatever reason, I just have the image. This causes the UpdatePanel to always do a full postback.

AJAX :: Full Page Postback Using Login Control?

Apr 14, 2010

I'm using an UpdatePanel (with UpdateMode conditional) and in the ContentTemplate I've got a Login control. Even though the control is embedded in the UpdatePanel as soon as the Login-button is hit a full page postback is being done. I've read some posts on the subject indicating that these controls are incompatible - but these posts already date from 2 years ago. Does anybody have more recent information on the subject?

AJAX :: Mozilla Does A Full Page Postback And Refreshes The Whole Page

Feb 10, 2010

Im implementing a simple form with ajax to warn the user if email has been used or not for registration, and it looks to be working fine with IE but mozilla does a full page postback and refreshes the whole page.

I already tried changing to updatemode to conditional, all the triggers are set as async, etc but mozilla keeps doing the same, Im sure it is a known problem I may not be the first one facing this problem so i guess there is a simple workaround for this.

AJAX :: Modal PopUp's OkClick Causing Full Page Postback?

Apr 28, 2010

AJAX :: Page Inside Update Panel Doesn't Refresh The Session Object After Postback Of Any Control

Oct 1, 2010

I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.

Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

AJAX :: Web User Control Loaded Into PlaceHolder Control Causing Full Postback On Parent Page?

Jun 1, 2010

In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.

When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.

how to capture this post so its rendered in Ajax and not a full post back?

C# - AsyncFileUpload Postback Does Not Do A Full Page Postback?

Jul 6, 2010

I implemented the AsyncFileUpload control on a web page. This web page requires uploaded files to appear in a gridview. The gridview contains the following columns: "File Name", "Confidential" Check Box, and a "Remove" button to remove the uploaded file.

Since the AsyncFileUpload postback does not do a full page postback, I need to "force" a postback on the OnClientUploadComplete event of the AsyncFileUpload control in order to render the gridview after uploading a file. In the OnClientUploadCompleteevent, I use javascript to call __doPostBack. In this postback, I only bind my gridview and display the file information (I don't re-save the file).

The problem: On the AsyncFileUpload's first "partial" postback, the file is successfully uploaded, as expected. On the second postback that I force with __doPostBack, the file is re-uploaded. You can verify this by using Google Chrome, which displays the upload progress. The behaviour is as follows: After selecting the file, the progress increments from 0% to 100% and the file is uploaded. After this, the __doPostBack executes, and you can see the upload progress increment again from 0% to 100%.

How can I make sure the Gridview is properly populated, but that the file is not uploaded twice?

I attached a sample solution which contains the issue:

AJAX :: Full PostBack In EndRequestHandler?

I have an UpdatePanel with a button that, when clicked, calls a WebService. I attached an UpdateProgress to it that shows a "loading" gif while it runs. Everything works fine, but I need a full PostBack once the operation is complete because I'm using my company's custom template that displays an info message and enables a "Next" button upon completion.I've had partial success with the endRequestHandler but I'm not sure what to put in my function to force a full postback once the UpdatePanel has run its course. I'm getting into the endRequestHandler function but I have been unable to successfully get a full PostBack.Here is my current code (including several attempts), the bottom part being the focus:

AJAX :: Update Panel Doing Full Postback?

Oct 20, 2010

I am having an issue with an update panel, which is still causing the entire page to postback.

I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.

I am using a master page, but the update panel only appears in the content page, within the content tags.
